UUs let you believe whatever you want but they have 7 principles which are:
The inherent worth and dignity of every person;
Justice, equity and compassion in human relations;
Acceptance of one another and encouragement to spiritual growth in our congregations;
A free and responsible search for truth and meaning;
The right of conscience and the use of the democratic process within our congregations and in society at large;
The goal of world community with peace, liberty, and justice for all;
Respect for the interdependent web of all existence of which we are a part.
